Abstract
The utility model discloses an oil -free lubrication's slide bearing, locate the interior bearing inner race of bearing inner race including bearing inner race and cover, bearing inner race is equipped with the corrosion resistant alloy powder, the last a plurality of through -hole that is equipped with of bearing inner race is equipped with the ball on this through -hole, circular motion can be to the ball in the through -hole to this ball surface coating PTFE slides on bearing inner race, the utility model discloses a structure of ball, it is little to start frictional resistance to spraying wear -resistant material PTFE on the ball increases the life of ball, and be equipped with cr50 chromium base alloy powder at bearing inner race, it is corrosion -resistant, high temperature resistant, the life of multiplicable whole bearing.
Description
Technical field
This utility model belongs to technical field of engineering machinery, is specifically related to the sliding bearing of a kind of oil-free lubrication.
Background technology
Sliding bearing, the bearing worked under sliding friction, sliding bearing stable working, reliable, noiseless, sliding bearing application scenario is typically under low-speed heave-load working condition, or maintaining and the operating position of charging-up lubricant oil difficulty；The most conventional sliding bearing, in order to reduce friction, increases service life, uses hydrodynamic lubrication more, slidingsurface separately is not occurred directly to contact by lubricating oil, can reduce friction loss and surface abrasion, oil film also has certain vibration absorption ability, but starting friction resistance is bigger.
Utility model content
Utility model purpose: the problem existed for prior art, this utility model provides the sliding bearing of a kind of oil-free lubrication little, corrosion-resistant, resistant to elevated temperatures that rubs.
Technical scheme: the sliding bearing of a kind of oil-free lubrication, including bearing outer ring and the bearing inner race that is sheathed in bearing outer ring, described bearing inner race is provided with corrosion resisting alloy powder；Described bearing inner race is provided with several through holes, and this through hole is provided with ball, and ball can move in a circle in through hole, and slides on bearing outer ring, this ball surface spraying PTFE.
Specifically, described bearing outer ring and bearing inner race are stainless.
Specifically, the through hole on described bearing inner race is grid-shaped arrangement.
Specifically, the diameter of described ball adapts with the width of through hole.
Specifically, described corrosion resisting alloy powder is Cr50 chromium-base alloy powder.
Beneficial effect: compared with prior art, the utility model has the advantage of: using the structure of ball, starting friction resistance is little, and spraying wear-resistant materials PTFE on ball, increases the service life of ball；Secondly, it is provided with Cr50 chromium-base alloy powder at bearing inner race, corrosion-resistant, high temperature resistant, the service life of whole bearing can be increased.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
As shown in Figure 1, the sliding bearing of a kind of oil-free lubrication, is stainless steel including bearing outer ring 1, bearing inner race 2 and ball 3, bearing outer ring 1 and bearing inner race 2, bearing inner race 2 is sheathed in bearing outer ring 1, and leaves certain gap between bearing inner race 2 and bearing outer ring 1；Bearing inner race 2 is provided with corrosion resisting alloy powder, and this corrosion resisting alloy powder is Cr50 chromium-base alloy powder；Bearing inner race 2 is provided with several through holes of marshalling, these arrays of openings are latticed, each through hole is provided with a ball 3, ball 3 can move in a circle in through hole, and slide on bearing outer ring 1, the width of through hole adapts with the diameter of ball 3, one layer of wear-resisting PTFE of the surface spraying of ball 3.
